A Prescott, Wis., man was allegedly on his cellphone when he lost control of a truck last year and crashed into a car, killing the other driver.

Thomas E. Geistfeld, 65, was charged Oct. 2 in St. Croix County Circuit Court with homicide by negligent operation of a vehicle and second-degree reckless homicide in the death of Dawn M. Anderson.

The crash occurred when Geistfeld, driving a Chevrolet K3500, attempted to pass a truck pulling a trailer shortly before 8 a.m. Sept. 27, 2011, on County Highway I in the Town of St. Joseph. Geistfeld told investigators he lost control of the truck, fishtailed, and then hit the oncoming Toyota Corolla driven by Anderson, according to the criminal complaint.

Anderson, 37, of New Richmond, died at the scene.

A passenger in the K3500 told investigators Geistfeld was on his cellphone when he lost control of the truck, at which point Geistfeld threw down the phone and tried to regain control, the complaint states.

The road was wet at the time of the crash and an accident reconstruction determined Geistfeld was driving between 73 and 94 mph, according to the complaint.
